I've been trying to recreate the main grey sphere in this image:

enter image description here

My guess so far is that the approach should be to decimate an icosphere, then inset and scale down to make the crevasses. If that's the best approach, I can't figure out how how to get nice variability in the size of the faces.

Is my idea there right, and if so how can I achieve that geometry?

The Cell Fracture add-on would be a good start.

(The Cell Fracture add-on comes with Blender, all you have to do, is activating it via Menu -> Edit -> Preferences -> Add-ons)

  1. Create a sphere (icosphere or rounded cube work best) with a decent polycount.

create icosphere with 5 subdivisions

  1. Initiate Cell Fracture via F3 - Search - Cell Fracture.

    In the settings dialog under "Own Particles" - "Point Source", change the Source Limit to 50 and under "Recursive Shatter", change the Recursive Subdivision to "Big" and hit "OK".

Cell Fracture Settings

  1. Hide the original sphere, then select all objects with "_cell" in their names.

    Go to the "Transform Options" dropdown menu and check "Locations". This will provide us with the option to "explode" the individual objects away from their origins, which in our case is the center of the original sphere.

Transform Settings

  1. Hit S and scale the selected objects, until the desired gap size is reached.

Scale Sphere Fragments

  1. You can then unhide the original sphere and proceed from there with additional modifications (decimate, boolean, etc)

After Scaling and Basic Material Setup

With Decimate Modifier on all Fragments
